(WS) collected Light Detection and Ranging (LiDAR) data for the USDA Forest Service on September 17, 2007. The project covers an 8-mile reach of the Powder River in northeast Oregon, downstream of the town of Sumpter. The extent of requested LiDAR area totals over 3,146 acres; the map below shows the extent of the LiDAR area to be delivered, covering nearly 3,208 acres. The delivered acreage for the study area is greater than the original amount due to buffering of the original AOI and flight planning optimization.Provide high resolution terrain elevation and land cover elevation data.Please credit the Puget Sound LiDAR Consortium (PSLC) for these data.

NOAA Coastal Services Center.datasetHorizontal Positional Accuracy ReportHorizontal positional accuracy for LiDAR is dependent upon the quality of the GPS/INS solution, sensor calibration and ground conditions at the time of data capture. The standard system results for horizontal accuracy are less than 1 meter.

Figure 2 below illustrates the location, swath width and the overlap of the planned flight lines for the Sumpter AOI. A real-time kinematic (RTK) survey was conducted in the study area for quality assurance purposes. The accuracy of the LiDAR data is described as standard deviations of divergence (sigma ~ s) from RTK ground survey points and root mean square error (RMSE) which considers bias (upward or downward). These statistics are calculated cumulatively.Acquisition. The LiDAR survey utilized a Leica ALS50 Phase II mounted in Cessna Caravan 208B. The full survey was conducted September 17, 2007. The Leica ALS50 Phase II system was set to acquire =105,000 laser pulses per second (i.e. 105 kHz pulse rate) and flown at 800 meters above ground level (AGL), capturing a scan angle of plus\minus 14o from nadir2. These settings are developed to yield points with an average native density of =8 points per square meter over terrestrial surfaces. The native pulse density is the number of pulses emitted by the LiDAR system. Some types of surfaces (i.e., dense vegetation or water) may return fewer pulses than the laser originally emitted. Therefore, the delivered density can be less than the native density and lightly variable according to distributions of terrain, land cover and water bodies.2007-09-17T00:00:001. Resolve kinematic corrections for aircraft position data using kinematic aircraft GPS and static ground GPS data. 2. Develop a smoothed best estimate of trajectory (SBET) file that blends the post-processed aircraft position with altitude. 3. Calculate laser point position by associating the SBET position to each laser point return time, scan angle, intensity, etc. Creates raw laser point cloud data for the entire survey in *.las. 4. Import raw laser points into manageable blocks (less than 500 mb) to perform manual relative accuracy calibration and filter for pits/birds. Ground points are then classified for individual flights lines (to be used for relative accuracy testing and calibration). 5. Using ground classification points per each flight line, the relative accuracy is tested. Automated line-to-line calibrations are then performed for system attitude parameters (pitch, roll, heading), mirror flex (scale) and GPS/IMU drift. Calibrations are performed on ground classified points from paired flights lines. Every flight line is used for relative accuracy calibration. 6. Position and attitude data are imported. Resulting data are classified as ground and non-ground points. Statistical absolute accuracy is assessed via direct comparisons of ground classified points to ground RTK survey data. Data are then converted to orthometric elevations (NAVD88) by applying a Geoid03 correction. Ground models are created as a triangulated surface and exported as ArcInfo ASCII grids at a 1-meter pixel resolution.The NOAA Coastal Services Center (CSC) downloaded topographic files in LAZ format from PSLC's website. The files contained lidar easting, northing, elevation, intensity, return number, class, scan angle and GPS time measurements; the data was received in UTM Zone 11 (in meters) and vertical coordinates were referenced to NAVD88 in meters using the Geoid03 model. CSC performed the following processing for data storage and Digital Coast provisioning purposes: 1. The All-Return LAZ files were checked for bad elevations 2. The laz files were converted from a Projected Coordinate System (UTM Zone 11) to a Geographic Coordinate system (NAD83) 3. The laz files were then converted to ellipsoidal vertical units in meters.2013-11-20T00:00:00DOC/NOAA/NOS/OCM > Office for Coastal Management, National Ocean Service, National Oceanic and Atmospheric Administration, U.S. Department of Commerce843-740-12002234 South Hobson Ave.CharlestonSC29405-2413coastal.info@noaa.govhttp://coast.noaa.govprocessorThe NOAA National Geophysical Data Center (NGDC) received lidar data files via ftp transfer from the NOAA Coastal Services Center. The data are currently
being served via NOAA CSC Digital Coast at http://www.csc.noaa.gov/digitalcoast/. The data can be used to re-populate the system. The data are archived in LAS or LAZ format.
The LAS format is an industry standard for LiDAR data developed by the American Society of Photogrammetry and Remote Sensing (ASPRS); LAZ is a loseless compressed version of
LAS developed by Martin Isenburg (http://www.laszip.org/). The data are exclusively in geographic coordinates (either NAD83 or ITRF94). The data are referenced vertically to
the ellipsoid (either GRS80 or ITRF94), allowing for the ability to apply the most up to date geoid model when transforming to orthometric heights.2013-12-06T00:00:00Mike SutherlandDOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commerce303-497-6120303-497-6513NOAA/NESDIS/NGDC E/GC1 325 BroadwayBoulderCO80305-3328USAmike.sutherland@noaa.gov7:30am-5:00pm Mountainprocessorannually2014-12-06This metadata was automatically generated from the FGDC Content Standards for Digital Geospatial Metadata standard (version FGDC-STD-001-1998) using the 2013-01-04 version of the FGDC RSE to ISO 19115-2 for LiDAR transform.Translated from FGDC 2013-12-06T16:45:25.47-05:00
